HOT-AIR REGISTER AND .VENTILATOR.

' srnoIrIcA'rIoN form ng part of Letters Patent No. 436,522,

dated September 16, 1890.

Application filed April 14-, 1890. Serial No. 847,890. (No model.)

To aZZ whom it may concern:.

Be it known that .I, J OSEPH GnDDEs, of Rochester, in the county ofMonroe and State of New York, have invented a certain new and usefulImprovement in Hot-Air Registers and Ventilators; and ,I do herebydeclare that the following is a full, clear, and exact description ofthe same, reference being had to the drawings accompanying thisapplication.

My improvement relates to registers and ventilators set into the sidewalls of rooms 5 and it consists, more particularly, in the employmentof a wing or valve that covers the whole opening of the face-plate,being hinged so as to be swung open and closed, and arranged to be heldin either position by the means hereinafter described.

In the drawings, Figure I is a front elevation of a register providedwith my improvement. Fig. 2 is a similar view of the interior frame andwing, the face-plate being removed. Fig. 3 is a central verticalcross-section in line as a: of Fig. 1, showing in full lines the Wing orvalve in its closed position, and in dotted lines the same part in itsopen position. Fig. 4 is an elevation of the adjusting-rod and itscrankconnections removed from the register. Fig.

5 is a front elevation of the arrangement at the bottom of the registerfor adjusting and holding the wing. Fig. 6 is a perspective view of thesame.

A indicates the hot-air box, which is located in the side wall of theapartment, and B is the hot-air pipe connected therewith, the same beingof ordinary form and construction.

0 is the inner frame of the register, which is attached to the openfront of the box, and D is the open face-plate attached to the frame byscrews or otherwise, so as to be removable. This may be ornamented inany desired way, one form being shown in the face view, Fig. 1,,sufficient opening being made through the face-plate for the escape ofthe hot air outward into the room.

In ordinary registers of the kind now in use, the openings through theface-plate are covered by vertical slats which are hinged so as to openand close, and as a number of such slats are used they occupyconsiderable space, and much of the opening is covered and obstructed,even when they are open. I employ in place of these slats a single plateE, made of suitable material, forming a wing or valve, which, when open,exposes the whole opening of the face-plate, allowing unobstructedpassage of the hot air, and when closed covers said opening and preventsany escape. This wing is hinged at the top, as shown at a, and swingsbackward, so as to cut off more or less of the heat, as indicated bydotted lines in Fig. 3. In this position it forms a deflector to throwthe hot air directly outward without passing to the top of thebox. Itcan be set at any angle to regulate the passage of the hot air, by themeans hereinafter described.

F, Figs. 5 and 6, is a casting forming a bearing in the bottom of theframe 0, and G isa rod or spindle hinged at its upper end to the top ofthe wing E, above thehinge a, on which the wing turns, the lower end ofsaid rod passing down loosely through a hole in the top of the bearingF, and having swiveled thereto a crank-arm II, which projects outwardthrough an opening 0 in the front of the bearing, and in position to bereached and operated by the hand. On one side of this opening is acrossslot (1, of sufficient size to receive and hold the crank-arm whenraised and turned to one side, and on the other side of the opening is aslotted plate f, forming a stop held in place by a set-screw g, whichpasses through the slot and enters the bearing. By this means theslotted plate can be adjusted higher or lower, and fixed at anyposition, as indicated by the dotted lines in Fig. 5. The crank-arm H isalso adapted to be turned in the opposite position and rest under theend of this gageplate.

To close the wing or valve E, the spindle G is pressed up, and thecrank-arm H is then turned to the left into the side slot (1, whichlocks it in place and holds the spindle elevated. To open the wing, thecrank-arm H is pressed down,carrying the spindle with it, and is thenturned to the right under the lower end of the gage-plate f, which holdsit in that position. By making the gage-plate vertically adjustable, asbefore described, the degree of opening of the valve can be regulatedexactly as desired. Under some circumstances it is desirable to limitthe opening of the valve to only a part of the depth of the hot-air box.When used as a ventilator, the valve is hinged at the bottom and theleverwork reversed, so as to operate from the top.

The register may be of any desired shape-- square, rectangular, oroblong.

The device is effective for furnace, steam, or hot-Water heating.

It is obvious that the spindle G can be hinged at its top to the wing E,either above or below the hinge a, on which the wing swings. If hingedbelow, the wing will be opened by the raising of the spindle and closedby its falling. 7 I

I design to make an opening in the faceplate D, opposite the screw 9, sothat the screw can be turned by a screw-driver without removing theface-plate.

Having described my invention, What I claim as new, and desire to secureby Letters Patent, is

1. In a hot-air register, the combination, with the face-plate D, of thewingor valve E, hinged at its top so as to swing forward and back, thespindle G, hinged to the Wing, and the crank-arm H, swiveled t0 thelower end of the spindle and capable of being turned to the right andleft to engage with devices for looking it in place, as herein shown anddescribed.

2. In a hot-air register, the combination, with the face-plate D, of thewing E, hinged so as to swing forward and back, the spindle G, hinged tothe wing, the crank-arm H, swiveled to the lower end of the spindle andcapable of turning to the right and left, the bearing F, provided withthe cross-slot d, into which the crank-arm turns when elevated, and thegage-plate f, under which it turns when depressed, as shown anddescribed, and for the purpose specified.

3. In a hot-air register, the combination, with the face-plate D, of thewing E, hinged so as to swing forward and back, the spindle G, hinged tothe wing, the crank-arm H, swiveled to the lower end of the spindle andoapable of turning to the right and left, the bearing F, provided withthe cross-slot d, and the gage-plate f, adjustable higher or lower bythe set-screw g, as shown and for the purpose specified.

In witness whereof I have hereunto signed my name in the presence of twosubscribing. witnesses.
